The Effect of Narrow Field of View and Information Density on Visual Search Performance in Augmented Reality
2019 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)(2019)
摘要
Many optical-see-through displays have a relatively narrow field of view. However, a limited field of view can constrain how information can be presented and searched through. To understand these constraints, we present a series of experiments that address the interrelationships between field of view, information density, and search performance. We do so by simulating various fields of view using two approaches: limiting the field of view presented on a Microsoft HoloLens optical-see-through head-worn display and dynamically changing the portion of a large tiled-display wall on which information is presented, for head-tracked users in both cases. Our results indicate a significant effect of information density and field of view on search performance, with potential search performance benefits of using a larger FOV between ca. 7-28%. Furthermore, while grids guided visual search, they did not significantly affect performance.
